CAR-AXLE BOXES.

153,554, dated July 28, 1574 application filed June 3, 1874.

To all whom it may concern:

Be it known that we, JOHN FERN and VAL- ENTIN ERBACH, both of Hyde Park, in the county of Luzernev and Sta-te of Pennsylvania, have invented a new and Improved Self- Lubricating Axle; and we do hereby declare under the inner portion of the journal, and

connected at the other end, by a pitman, with a wrist-pin eccentrically located on the outer end of the journal, vertically-oscillating motion being' thus givensaid roller,which causes its smaller end to be alternately immersed in the oil of a suitable reservoir, and raised, so that its whole periphery comes into rolling contact with the under side ofthe journal, thereby lubricating the latter, the conical form of the roller serving to distribute the oil along its entire periphery.

Our invention further consists in the employment of a screw-threaded socket tting over the wristfpin, which receives the screwthreaded lower end ot' the pitman, by which construction the movement of the conical roller may be varied at pleasure to regulate the dip' into the oil. p

'In the drawings, A represents the journal of the axle; B, the axle-seat or top bearing and C, the conical porous or elastic roller, The latter is hinged to suitable ears or projections F on the back side of the casing G, immediately under the journal A, and extends along the Linder side of said journal to its outer end, where it is connected by a pitman, H, screw-threaded at its upper end, and secured to a screw-threaded socket, s, on a wrist-pin, I, eccentrically located on the end of the journal, as shown.

Vhen the journal revolves, it will be seen that the outer end of the roller C is alternately depressed and elevated. When depressed, it is dipped into an oil-chamber, J, below 5 and, when elevated, it is pressed against the lower side of the journal, the shaft C, pitman H, and pin I being so arranged that whenraised to its utmost extent the upper side of the roller is parallel with the journal, and its entire length is pressed against the latter, causing it to revolve as long as the contact lasts.

The length of the pitman may be regulated by its screw-connection with the socket, thus varying the amount of oil raised.

The roller C is composed ot' rubber, sponge, or other elastic or fibrous material. When raised so that its upper side is horizontal its lower side inclines downward from the outer end, by reason of its conical shape. Hence the oil ows from the outer to the inner end, and lubricates that portion which does not come in contact with the oil. The journal is contact with the roller, which occurs once during every revolution of the journal, and is amply sufficient to keep the latter well oiled. We are aware that a rod bent at right angies, and having one of its ends swiveled to the axle-support, and its opposite end attached, by a jointed connection, with a pin eccentrically situated on the end of the axle, the horizontal portion of the` rod being provided with fibrous material, which is made oil, and` then convey the latter to the under surface of the axle, has heretofore been employed, and we therefore lay no claim to such invention.

We claim as our invention- 1. The hinged conical roller C, in combination with the pitman H, wrist-pin I, attached eccentrically to the axle, and oil-chamber J, substantially as described, and for the purpose set forth.

2. The hinged conical roller C,.in combination with the adjustable pitman and socket S, axle, and oil -chamber J, substantially as described.
